and even under grazing produces significant levels of viable seed that end up in the soil (Chapman and AnderWhite clover (Trifolium repens L.) populations persist for years in son, 1987; Charlton, 1977). grazing lands primarily through clonal growth, yet retain high genetic variability. This study was conducted to determine how clone structure In spite of the presence of viable white clover see...

The Face-to-Face Composition (FFC) Model is a modular, boundary-based description of an object. The Assembly AND/OR graph proposed by Homem de Mello and Sanderson for task planning is an efficient data structure showing all possible assembly sequences. It can be obtained directly from the FFC model by a sequence of component-merging operations.

A 28 year old albino man presented with a cicatricial alopecic plaque on the vertex. The patient had multiple hairs emerging from a single dilated follicular opening. Following inflammatory changes, new tufted hair appeared in spite of several periods of antibiotic treatment, and the disorder followed a relapsing and destructive course. Tufted hair folliculitis (THF) is a relapsing localiz...

The teichoic acids in and beneath the walls of staphylococci are particularly interesting, not only with regard to structure and function but also because of their serological properties. The groupantigenic polysaceharide A from Staphylococcus aureus is indistinguishable from the wall teichoic acid from that organism, and a similar preparation from S. albi4s strains is serologically indistingui...
